| 摘 要： | 以20世纪70年代陆地卫星MSS和90年代ETM图像为基础,通过分析对比,并配合野外检查验证,快速提取了塔里木盆地周边地区4种程度土地沙化类型的分布信息.根据获取的两个时期4种程度的土地沙化类型分布信息,编制了全区土地沙化程度及范围变迁图.该图客观地反映了区内近30a来土地退化的实际情况,为干旱-半干旱地区的土地退化研究提供了遥感技术应用实例. |

| Abstract: | On the basis of Landsat MSS of 1970s and ETM image of 1990s and by means of analysis and comparison as well as field inspection, the authors rapidly extracted the distributive information of four levels of soil desertification along the peripheral areas of Tarim basin. According to the available distributive information of four levels of soil deterioration in two periods, a map showing the gradual change of the extent and limits of soil desertification in the whole region was compiled, which objectively reflects the land deterioration in the past 30a and provides a remote sensing application example for the study of land deterioration in arid and semi-arid areas. |
| Keywords: | Soil desertification Image character Map of gradual changes Deterioration |
